Medicare Exclusion Database (MED) File

The NBCP is tasked with identifying efficient, effective and economical ways to conduct comprehensive background checks of all prospective direct access employees of long term care (LTC) facilities and providers. Each State awarded a grant under the NBCP is charged with implementing and administering a Statewide program that includes a fingerprint-based State and federal criminal history check and the search of various registries including the required Office of Inspector General’s List of Excluded Individuals and Entities (OIG LEIE).

With the support of technical assistance (TA) through the NBCP, many participating States are using automated processes to conduct the various screenings including a name-based check through the OIG LEIE website.

This check brings back the closest match(es) to the information provided by the user. However, with this search, human intervention is required to review the results and determine whether there is a true match. To further automate the process, CMS and the NBCP TA team looked to the use of the Medicare Exclusion Database (MED), an enhanced version of the OIG LEIE, to complete the search. Commonly called “the MED File,” this CMS system of record is distributed monthly to each State’s Medicaid agency. Unlike the LEIE, the MED File includes Personally Identifiable Information (PII) such as an individual’s Social Security Number (SSN) and date of birth (DOB). Using this file to complete the LEIE search essentially eliminates the need for a manual review as the search can produce an exact match and ultimately make an automatic “CLEAR” or “NOT CLEAR” determination. Automating the match greatly reduces the response time and expenses by significantly decreasing the number of false matches. Additionally, participating States have the ability to do automated registry rechecks monthly of the MED File to search for any new information on individuals currently in their data system, thus providing additional protections for vulnerable populations.

Several NBCP States are currently accessing the MED File through their automated background check systems. State background check staff note several efficiencies and added protections using the MED File versus the OIG LEIE manual lookup. The first notable efficiency is automation versus a manual search. When a registry check is initiated, a search of the MED File is automatically completed and a “Clear” or an exact data match is returned within seconds. This response time far exceeds the manual process to click a link accessing the OIG LEIE, typing in the personal identifying information for each applicant and reviewing each returned record to determine if there is a match.

A second evident efficiency is a reduction in the number of false positives avoided by using the SSN-based MED File instead of the name-based OIG LEIE. For example, since inception of the ARCS system in Ohio, 79,896 applicants have been checked against the MED File with zero matches returned. In comparison, the same applicants were run through a name-based registry search of the OIG LEIE and 186 matches were returned. Thus, using the MED File prevented the time-consuming review of 186 false positive results, saving valuable staff time to confirm the identity of each record.

The MED File process also represents an additional safeguard in ensuring applicants are appropriate and fully qualified to provide LTC services. Because the MED File process is fully automated, States using this process are no longer dependent on remembering to manually upload the monthly updated OIG LEIE file. Recently, an NBCP grantee State using the OIG LEIE had not updated the file in several months. It was later found that a person was previously cleared to work in LTC was in fact on the OIG LEIE and therefore should have been denied employment. With the automatic FileWatch feature used by the MED File process, the grantee state could have avoided this situation.

The MED File process is efficient and effective and can be replicated in any background screening check program with the appropriate DUA approval.
